[QUOTE="chris, post: 6414, member: 352"] I just saw this thread as I was on holiday for a few weeks. I?ve built quite a few 2 axis systems. However, they all were controlled to work in 90 degs only. (Grinding, welding and scanning). We use dc motors (Nissan 1400 wiper motor is almost indestructible even at 20v) with encoder feedback. In many of the prototypes we used normal threaded rod, with great success. Only problem is the pitch of the thread, as this leaves you with a big gear ratio, so you need a faster motor. Ball screws and linear bearings are very expensive but if you want accuracy there is nothing better. We?ve been trying to make our own slides many of times with varied success using small bearing in extrusions, but always go back to the real stuff. This still sounds like a very good idea and I will surely look into the possibilities some more [/QUOTE]
